Airport HistoryEst. 1955
O'Hare began life in the early 1940s as Orchard Field, a wartime airstrip built for Douglas Aircraft's C-54 transport plant, which is why its IATA code is still ORD. Renamed in 1949 for Navy flying ace Edward 'Butch' O'Hare, it grew through the jet age into one of the world's busiest airports and remains a major hub for United and American Airlines.
The site was developed during World War II as an airfield attached to a Douglas Aircraft plant producing C-54 Skymaster transport planes, the origin of the ORD airport code.
Chicago renamed the airport in honor of Lieutenant Commander Edward 'Butch' O'Hare, a U.S. Navy fighter pilot and Medal of Honor recipient killed in World War II.
Scheduled airline service started at O'Hare as Chicago began shifting traffic away from the smaller Midway Airport.
O'Hare surpassed Midway as Chicago's main airport and rapidly became one of the busiest airports in the world during the jet age.
An American Airlines DC-10 crashed on takeoff on 25 May 1979, killing 273 people in what was then the deadliest single-aircraft aviation disaster in U.S. history.
Terminal 5, O'Hare's dedicated international terminal, opened to accommodate growing overseas traffic.
After decades atop the rankings, O'Hare was overtaken by Hartsfield-Jackson Atlanta International Airport as the world's busiest by passenger traffic.
As part of the O'Hare Modernization Program, a new runway opened, the airport's first in decades, part of a long-term reconfiguration of its runway layout.
